A three position lift chair goes one step further than the two position lift chair in that it can almost reach a full incline. We stress almost here because the three position lift chair doesn't achieve a perfect horizontal line. There is a slight "V" where the back and seat meet. This chair is perfect for watching television and napping. The three position lift chair isn't limited to three positions. It can recline to any position in-between straight and it's fully reclined position.
